Teng:
It sounds like your application consists of 'boilerplate'
html (lots of static html with a few simple variable
replacements for name, address, etc...).
If this is this case, then JSP will suit you very nicely.
No need to use println statements at all.
You'll need to write a bean that provides getter
methods to retrieve the value(s) you want to
plug in to your html (e.g. getName(), getAddress() ).
Then you can write a jsp file that looks
something like this:
<%@ page language="java" import="com.mydomain.*" %>
<jsp:useBean id="customer" scope="request" class="com.mydomain.Customer"/>
<jsp:setProperty name="customer" property="*"/>
<html>
<head><title>Customer <jsp:getProperty name="customer"
property="name"/></title></head>
<body>
Customer name: <jsp:getProperty name="customer" property="name"/><br>
Address: <jsp:getProperty name="customer" property="address"/><br>
</body>
</html>
The above jsp file will populate all properties of the
Customer from request parameters (that came from a
POST or GET request via a user form).
Note that '<jsp:getProperty name="customer" property="address"/>' will be
replaced with
the value returned by the call to "customer.getAddress()" where "customer"
is defined
as:
com.mydomain.Customer customer = new com.mydomain.Customer();
There is alot more to JSP's than this. It's best to pickup a good book
(I like Professional JSP from Wrox press) and delve into the details.
I hope this helps.
Good Luck
Tom

| Hi tom,
|
| thanks for your response.
|
| Actually my question is very simple: if I use
| FrontPage to create a html file, and I want to dump
| this html file with a little bit change (e.g. name,
| address,etc), then should I use println to do it? If
| it is the only choice, then I have to accept it.
|
| All the books about jsp or servlet I have gone through
| in the book store are always giving simple examples
| using println, I can't image I could follow this
| approach to create html file as I could no way control
| the layout. There should a tool like FrontPage so I
| could create whatever pages I want with images, text,
| different fonts, colors etc., then I could dump this
| html file into web browser with my own modification
| through jsp or servlet. Starting Hello World with c,
| you have a new C world, but with jsp,you can't go far
| as you can't use println to control layout which is
| crucial for web browser.
